WHEEL.

Application filed March 7, 1921. Serial No. 450,211.

To all wiwmitmag concern: I i

e it known that I, OTTOE. WILsON, a

citizen of the United States, residing at Peru, in the county t Miami and State of Indiana, have in ented new andusetul Improvements in Wheels, 0t which the tollowing is a specification.

This invention relates to resilient wheels and has for an object the provision ot a wheel 0t this Character in which'a cushioning member in the torm ot a pneumatic tire is employed, the latter being arranged so as not to engage the ground, whereby wear and puncture will be avoided, at the same time the tull cushioning effect of the tire will be utilized. p i

In carrying out the above, the invention contemplates the provision of a wheel of novel structure in which the cushioning member or pneumatic tire is protected within a housing, the said pneumatic member being carried by an extension of the wheel hub, which also serves as attaching means tor the protecting housing, while the latter provides means tor guiding a plurality of radially movable spokes whose inner ends bear against the pneumatic member.

The invention further includes the tollowing novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a side elevation ot a wheel embodying the present invention, parts being broken away to more clearly illustrate the construction.

Figure 2 is an enlarged sectional view on the line 2-2 of Figure 1.

Figure 3 is a tragmentary elevation of one ot the segmental spoke shoes.

Figure 4 is an elevation of one of the ra dially movable spokes.

Figure 5 is a detail of the lug tor gripping the rim.

Referring to the drawings in detail, wherein like characters otreterence denote corresponding parts, the invention as illustrated comprises a hub 10 and a telly 11, the latter being provided with a suitable rim 12 which may be permanently secured to the telly, or detachable as shown. This rim has secured thereto a tire 18, which is preferably solid, but it is of course obvious that a pneumatic tire may be employed if desired. The as 12 is detachably secured to the telly ot the wheel by means of rim lugs 14% which engage over annular flanges l5carried by the rim 12.

- The telly 11 is preferably channel-shaped in cross section andthe rim lugs are held in position by means of a bolt 16 which passes through openings provided in each side of the channel-shaped telly. Located within this telly is an annular member 17 which is also channel-shaped in cross section, the open edge of the channelbeing arranged 0p-' posite to that of the telly. Extending through registering openings 18 and 19 pro I,

vided in the telly 11 and the annular member 17 respectively,-is the reduced threaded end 20 ota spoke 21, as shoulder 22 tormed on the spoke engaging theinner periphery ot the telly 11, while the outer periphery of the annular member 17 is engaged by a nut 23 upon the threaded extension of the spoke. The said spoke is thus rigidly held connected to the telly. Any number ot these spokes may be employed, but it is believed that only three will be necessary.

Extending from the hub 10 is an annular extension 24, whose cross sectional width is less than the length ot the hub. This eX- tension has projecting from its outer periphery spaced annular flanges 25 tor engagement with the beads ot a pneumatic tire casing 26 ot the clincher type.

Secured to the inner ends 0t each of the spokes 21 is a segmental shoe 27 which is provided in one face with a socket 28 tor the reception otthe end of the spoke, the latter being secured within this socket by means ot a pin 29. The opposite tace ot the shoe 2? is shaped to conform to the tread ot the tire 26 with which it contacts, so that when the said tire is inflated relative movement of the telly and hub will be resisted and a cushioning efiect will result.

In addition to providing means for securing the cushioning member 26 in position, the annular extension 24 also provides means tor attaching to the hub a casing 30 which is adapted to surround and protect the outer or cushioning member, being bolt-' 26, the said casing also acts to guide the i 2 y .c 1,470,517

be closed by a plate 36 which is bolted to the annular extension 24 and to the casing proper as shown at 37 and 38 respectively. A tube 39 extending trom'the tire 36 to the outside of the casing provides means whereby air may be introducedto the tire 26, the outer'end of the tube being preferably pr0- vided with a cap 40 for protecting the same. It will be seen by reference tocFigure 2 of the drawings that the rim 12 which carries the outer tire 13 extends laterally beyond the sides of the telly and also beyond the ends of the bolts 16 for the protection of the latter.

The invention is susceptible of various 1 changesin its form, proportions and minor details of construction and the right is here iii-reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is A resilient wheel or".the character described comprising a hub, a hollow annular extension channel shaped in cross section surrounding the hub, spaced annular asso ciated flanges projecting from one wall of the extension, a pneumatic tire carrying in the flanges a metallic casing surrounding the tire and having its side walls secured to the side walls of the extension, one side wall of the casing being detachable. a right angled bent conveying tube partially arranged between walls of the extension and having one end communicating with the tire and its opposite end passing through one side wall of the extension and the detachable wall of the casing respectively, annularly spaced guides formed in the casing, spokes provided with lubricating grooves passing through the guides, lubricating cups formed on the guides and adapted to communicate with the grooves, a channel shaped member secured to the telly of the wheel, said spokes having reduced outer ends secured to the channel shaped member and a shoe carried by the inner end of the spokes and being designed to engage the tire as and for the purpose specified.

In testimony whereof I affix my signature.

OTTO EVERETT WILSON.
